The typographical errors are found in the following file starting on
line 818, AppendixC-OptionalTasks.html#L818]
The example under PhpDocumentorTask in the documentation misses
closing backslash on each of the four include-elements.
Furthermore, the 'sourcepath' attribute on the phpdoc element does not
exist; the attribute is called 'sourcecode' and should be set to 'no'
A working example should look like this:
<phpdoc title="API Documentation"
destdir="apidocs"
sourcecode="no"
output="HTML:Smarty:PHP">
<fileset dir="./Tests" >
<include name="**/*.php" />
</fileset>
<projdocfileset dir="." >
<include name="README" />
<include name="INSTALL" />
<include name="CHANGELOG" />
</projdocfileset>
</phpdoc>
